1. Product introduction of soil pH sensor

Soil pH sensor is also called soil pH sensor and soil pH sensor. The soil pH sensor is a soil sensor that can be directly inserted into the soil to accurately measure the soil pH value. It adopts a low-power sensitive chip, and the entire body is waterproof and dustproof. . FT-PH485 soil pH sensor solves the shortcomings of traditional soil pH that need to be equipped with professional display instruments, cumbersome calibration, difficult integration, high power consumption, expensive, and difficult to carry. It can be widely used in fields such as agricultural irrigation, flower gardening, grass pasture, quick soil measurement, plant cultivation, and scientific experiments. The PH10 has low power consumption and can be used for long-term uninterrupted monitoring. The sensor has the following characteristics:

The new soil pH sensor realizes online real-time monitoring of soil pH.

It adopts international advanced solid dielectric and large-area PTFE liquid junction, which is not easy to be blocked and maintenance-free.

Waterproof and sealed, high integration, small size, low power consumption, easy to carry, and can be used outdoors.

High precision, fast response, good interchangeability and reliable performance.

Perfect protection circuit and various signal output interfaces are optional.

model	wiring diagram
Voltage output type	Red (V+): Power supply is positive Black (G): power ground Blue (O1): output signal
Current output type	Red (V+): Power supply is positive Black (G): power ground Blue (O1): output signal
RS485 interface type Modbus protocol	Red (V+): Power supply is positive Black (G): power ground Yellow(T+): RS485+/A/T+ White(T-): RS485-/B/T- Sensor configuration parameters such as Modbus address, baud rate, check digit, communication protocol, etc. are stored in the EEPROM (power-down storage device) inside the module. Sometimes the specific configuration of these parameters will be forgotten, resulting in failure to communicate with the module. In order to prevent this problem, there is a button on the module. After pressing it for three seconds, the internal indicator light of the module will go out. When the button is released, all parameters of the module will be restored to the following factory settings: 1. Modbus address is 1 2. The communication configuration is 9600,N,8,1 (9600bps, no check digit, 8 data bits, 1 stop bit) The communication protocol is Modbus-RTU
